ALBERT S. GARLETON, OF CLINTON, MASSACHUSETTS.

MANUFACTURING COTTO-N FLANNEL.

Specification of Letters Patent No. 16,870; dated March 24:, 185'?.

To all whom t may concern:

Be it known that I, A. S. CARLETON, of Clinton, in the county ofW'orcester and State of Massachusetts, have invented a new and ImprovedMethod of Manufacturing Cotton Flannel and other Similar Napped Fabrics,of which the following is a full, clear, and exact description,reference being had to the annexed drawings, making part of thisspecification, in which- Figure l is a plan. Fig. 2 represents a section(enlarged) through the goods in a direction parallel to the filling uponthe line ae, az. Fig. 3, a similar section through the same upon a lineperpendicular to the filling `upon the line y, y, cotton flannel andother similar fabrics have heretofore been manufactured byV raising anap upon an ordinary tweeled single ply cotton. n

Then this fabric is woven in the ordinary way, it is not foundpracticable upon ne goods to raise a sufficient nap without. injuringthe strength of the fabric and such fabric will also be deficient vinwarmth and thickness.

To remedy these evils and to produce an article of cotton flannel offine texture that shall possess a heavy nap and great strength andthickness is the object of my present invention which consists inweaving a strong foundation for the fabric with a hard warp and fillingand in throwing in at every other pick upon one side of this foundationa soft heavy thread from which the nap is ultimately raised. I am thusenabled to furnish a great amount of nap without weakening the fabricand to produce a flannel thicker, warmer, and stronger than hasheretofore been practicable and of any degree of lineness required.

To enable others skilled in the art to understand my invention I willproceed to describe the manner in which I have carried it out.

In the accompanying drawings a are the warps, the filling threads whichmay be tweeled or otherwise woven together. As the weaving proceeds, aheavy soft yarn filling c is thrown in upon one surface of the fabric towhich it is tied by passing the warp threads at suitable intervals overit in a manner well known to weavers. Upon the surface of the fabricthus produced a nap is raised in the customary manner by means ofteazles. According to the quality of the cloth required a greater orless number of the soft yarns c, may be used in proportion to the numberof the foundation filling threads; this matter however being wellunderstood by weavers need not here be further discussed.

If a fabric of eXtra thickness and warmth be required, a soft yarn maybe laid upon both the Lipper and under surfaces of the foundation fabricand a nap raised upon both sides of the cloth.

I do not claim weaving a fabric with two species of fillings one only ofwhich shows upon each face, but

What I do claim as my invention and desire to secure by Letters Patentas a new article of manufacture, is-

The within described fabric or cotton flannel having a foundation ofhard thread and an eXtra filling of soft yarn `upon one or ifoth1 sidesfrom which a nap is raised as set ort i.
